Description
Power source VDD-VSS: Supply voltage for internal logic VDD-VEE: Supply voltage for VF display tube driving circuit logic Microcontroller Input of display data of the shift register Input from the MSB (positive logic). Shift clock of the shift register. Data is shifted at the falling edge of SCLK. Latch clock input for display data. When this pin is at a "H" level, the data is not latched to pass through the latch circuit. When the pin is at a "L" level, the data when the pin is at the "H" level is latched. -- Internal logic reset input upon power-on. During reset, the 18-bit internal latch, duty cycle register, digital register, LED register, and write/read address register are all reset, and the outputs of SEGA to SEGP(*a), D1 to D12 (*b), and LED1 to LED5 go off. Connecting of an external capacitor to the pin allows poweron reset. Input for oscillation circuit When an external resistor and a capacitor are connected, an oscillation circuit is formed.

*1: Ignored in the case of MSC7112-01 Inputting Display Data LED display Display data is output to the LED1 to LED5 pins in correspondence with each bit by executing www..com the L. RLOAD command. Input data uses positive logic. When the data is 1, the LED lights. When the data is 0, the LED goes off. VF display (RAM direct display) Set optional data in the digit register and the duty register, and execute the W.A.C LOAD command to set the display digit position. Execute the DATA DISPLAY command to write the b0 to b15 (*1) display data in the RAM. The write address counter is incremented by one. The write address counter counts sequentially 0, 1, 2,------, 14, 15, 0, 1, ----- regardless of the value of the digit register. *1 : b0 to b11 display data in the case of MSC7110-01. Brightness Adjustment The brightness can be adjusted by using the values of the duty cycle register (D.C.R) and the digit register (D.R). The value of the duty cycle register changes the pulse width (B) at the D1 to D16 output pins, and the value of the digit register changes the cycle (A). The table below gives the relation between the value of the duty cycle register and the duty. When all the values of the duty cycle register are 0 (in the case of 16-digit display), the display is blank.
